So today I removed the front bumper to reconnect the outside temp sensor, which still reads -40.0 even though the weatherman says its a warm 25... Anyhow this is not my question but would also like any advise on this issue. But while the bumber was off I also the following cable hanging down, I have attached a photo, please let me know what it is.

wow I just looked under and had the same wire hanging, was worried what this was as no EML lights are on and car runs fine so far as we just picked it up last Friday. Also has no AC so this has put my mind at rest now
Thanks Guys
